Survey Shows How Much Power Consumption Goes into Charging iOS Devices


iOS devices don’t cost all that much to charge, a recent study found. The Electric Power Research Institute (EPRI) found that charging a current-gen iPad every other day will cost consumers about $1.36 per year.

 The study was originally conducted to evaluate the power consumption in the US, but they decided to go ahead and figure out how the rise of tablets has affected consumption as well.

The older iPad models run at about 83 cents a year for the iPad 2 and 82 for the original iPad. The iPhone 3G is about 25 cents a year, and the iPhone 4 is 38 cents. The iPad nano? A mere 3 cents a year.
